Best CSS Frameworks for Building Better Websites
When building a website, using a CSS framework is a real time saver as it provides you with tools every web designer and front-end developer needs when crafting a site (other than good web hosting).
A CSS framework is a software framework created to allow for easier, more standards-compliant web design using HTML/CSS. Many popular CSS frameworks are design-oriented and contain elements that can be re-used in the creation of any website or app, as well as a grid system designed to provide a responsive CSS layout to webpages.
All the frameworks listed in this article are free and open source.
Without a doubt, Bootstrap is the most widely used free and open source CSS framework. Created in 2011 by developers Mark Otto and Jacob Thornton, Bootstrap is now used by millions of websites.
Bootstrap features Sass variables and mixins, a responsive grid system, extensive prebuilt components for building layouts, and powerful plugins built on jQuery.
Bootstrap is one of my tools of choice when it comes to building responsive websites or a WordPress theme. It’s extremely easy to learn and the documentation is very complete. If you want to become a web developer, learning Bootstrap is a must.

With 21kB minified and gzipped, Bulma isn’t the most lightweight of this list, but this open source CSS framework is so interesting that it totally deserves a mention. Bulma is built with a mobile-first approach, which makes every element optimized for vertical reading, and its grid system is fully built with Flexbox.
Achieving flexible layout with same-size columns is as simple as adding a
.column class to any of your HTML elements.
Bulma is also built with Sass, which allows you to only use the features you really need in your web development tasks.

Tailwind is a relatively new CSS framework, designed to be different from its competitors. Instead of predesigned components, Tailwind provides low-level utility classes that let you build your own designs.
Let’s have a quick look to some HTML used with Tailwind:
<button class="bg-blue hover:bg-blue-dark text-white font-bold py-2 px-4 rounded"> Button </button>
As you can see, the example is using many utility classes on a
button element. Those classes allow you to finely style any element: We can easily spot classes named
rounded, defining the visual aspect of the button.

Material Design is a design language created in 2014 by Google. It uses more grid-based layouts, responsive animations and transitions, padding, and depth effects such as lighting and shadows.
As of 2019, Material Design has been implemented on most Google products as such as YouTube, Gmail, Google Drive, and Google Docs.
Materialize is a modern responsive front-end framework based on Material Design. Easy to use, it provides components, as well as starter templates which allow you to start designing your website with minimal setup time.
